1. Blood components • Adults have 4-6 L of blood • A liquid connective tissue – plasma – matrix of blood • a clear, light yellow fluid – formed elements - blood cells and cell fragments • red blood cells, white blood cells, and platelets
1.Blood components Blood cells(formed elements)suspended in plasma Plasma (55%of whole blood) Buffy coat: leukocytes and platelets (<1%of whole blood) -Formed ①Withdraw blood ②Centrifuge Erythrocytes elements and place in tube (45%of whole blood)
